-->Your organization has turned on two-factor verification, meaning that your work or school account sign-in now requires a combination of your username, your password, and a mobile device or phone. Your organization turned on this extra verification because it's more secure than just a password, relying on two forms of authentication: something you know and something you have with you. Two-factor verification can help to prevent malicious hackers from pretending to be you, because even if they have your password, odds are that they don't have your device, too.

- Work or school account. If you're using a work or school account (for example, [email protected]), it's up to your organization whether you must use two-factor verification, along with the specific verification methods. Because your organization has decided you must use this feature, there is no way for you to individually turn it off.
- Personal Microsoft account. You can choose to set up two-factor verification for your personal Microsoft accounts (for example, [email protected]). If you're having problems with two-factor verification and your personal Microsoft account, see Turning two-factor verification on or off for your Microsoft account. Because you choose whether to use this feature, you can turn it on and off whenever you want.
